Abstract: 499,139. Photographic and kinematographic processes. TERRY, P. H. June 18, 1937, No. 16966. Convention date, June 18, 1936. [Classes 97 (i) and 98 (ii)] In photographing a scene comprising a projected background and a separate pictorial representation, for example in the preparation of kinematograph cartoons, an enlarged image of the background is projected to a plane adjacent the substantially opaque representation, and the projected rays are converged by optical means to the camera. As shown, the background projector 10 projects a cone of light 16 which is converged to the camera 18 by a lens 17 against which is a frame 23 having pins 24 to engage holes 28 in a cartoon cell 27, Fig. 3, which is transparent and carries an opaque representation 25 one surface of which bears detail. Lamps 29, 29<1> illuminate the detail on the front of the representation so that a single exposure will record the background together with the detail of the representation. Alternatively, an exposure may be made of the background only, the lamps 29, 29<1> being off, and then a second exposure made without the background. To prevent reflection from the lens 17 of light from the lamp 29, 29<1>, the latter may carry red filters, a green filter being placed between the lens 17 and the cartoon. Alternatively the lens 17 may be coloured, or polarizing filters may be employed. Coloured cartoons may be produced by this method.

Abstract: 709,682. Windscreen cleaners. TRICO PRODUCTS CORPORATION. July 7, 1952 [July 13, 1951], No. 17045/52. Class 138 (1) A windshield wiper of the kind wherein the blade is connected to an oscillible actuating arm, has a fin mounted on the blade or its holder, whereby air currents impinging on the fin produce a reactive pressure tending to press the blade into contact with - the windshield and to balance the lifting force of the air impinging on the other parts of the blade. As shown in Fig. 2, a transparent plastic fin 13 has trunnions 15, 16 journalled with limited play in bearings formed in an ear 17, turned up from the outer end of a secondary yoke 8, and in the end wall 18, Fig. 3, of a clip 11 for connecting a primary yoke 7 to the wiper arm 3. The ends 12 of the secondary yokes freely grasp a flexible backing 9 supporting a rubber squeegee 10. The trunnions 15, 16 may be encased in metal thimbles 20, 21, suitably secured, as by pressed fits or through a spline engaging a groove 23 in the trunnion. The fin has a stop 19 for engaging with the underlying yoke 8 and the stop is normally engaged with the yoke by a coiled spring 14, Fig. 3, connected at one end 24 to the thimble 21 and at its other end to the wall 18 at 25. In operation the wind currents flowing off towards the opposite sides of the windscreen and upwardly over the top thereof cause the fin to adjustably pivot away from its stopped position. When the wiper is parked the fin is in its normal position with the stop 19 abutting the yoke 8, and is out of the line of vision. In this position the fin is not actuated since an air pocket is formed beneath the air stream passing up over the windscreen.

Abstract: 1,064,076. Electron multipliers; image intensifiers. MULLARD Ltd. Feb. 12, 1964, No. 17280/63. Heading HID. In a channel intensifier device comprising a matrix in the form of a plate having elongated channels extending through its thickness between input and output electrodes provided on the major surfaces of the plate, the inner surfaces of the channels being resistive and secondaryelectron-emissive, at least one of the electrodes is sub-divided into two sets of parallel interdigitated conductors with the conductors of each set connected to a separate terminal. By applying a potential difference between the two sets of conductors, and between these and the other electrode, electric accelerating fields, which are inclined to the channel axes, are set up within the channels, whereby electron multiplication occurs on one side only of each channel, so that the length-to-diameter ratio of the channels is less critical. As shown, each electrode is formed by two sets of interdigitated conductors, the potential difference between conductors E1a, E1b being variable and equal to that between conductors E2a, E2b. The materials, manufacture and uses of the device may be similar to those described in Specifications 1,064,072, 1,064,073 and 1,064,074. Alternatively, the device may be formed from flat strips and corrugated strips arranged alternately and bonded together to form a rigid channelled block, the side edges of only the flat strips being rendered conductive to provide the interdigitated conductors, Fig. 4 (not shown).
